DESCRIPTION
       The QFileDialog class provides dialogs that allow users to select files
       or directories.

       The QFileDialog class enables a user to traverse their file system in
       order to select one or many files or a directory.

       The easiest way to create a QFileDialog is to use the static functions.
       On Windows, these static functions will call the native Windows file
       dialog and on Mac OS X, these static function will call the native Mac
       OS X file dialog.

	   QString s = QFileDialog::getOpenFileName(
			   "/home",
			   "Images (*.png *.xpm *.jpg)",
			   this,
			   "open file dialog",
			   "Choose a file" );

       In the above example, a modal QFileDialog is created using a static
       function. The startup directory is set to "/home". The file filter is
       set to "Images (*.png *.xpm *.jpg)". The parent of the file dialog is
       set to this and it is given the identification name - "open file
       dialog". The caption at the top of file dialog is set to "Choose a
       file". If you want to use multiple filters, separate each one with two
       semi-colons, e.g.

	 "Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"

       You can create your own QFileDialog without using the static functions.
       By calling setMode(), you can set what can be returned by the
       QFileDialog.

	   QFileDialog* fd = new QFileDialog( this, "file dialog", TRUE );
	   fd->setMode( QFileDialog::AnyFile );

       In the above example, the mode of the file dialog is set to AnyFile,
       meaning that the user can select any file, or even specify a file that
       doesn't exist. This mode is useful for creating a "File Save As" file
       dialog. Use ExistingFile if the user must select an existing file or
       Directory if only a directory may be selected. (See the
       QFileDialog::Mode enum for the complete list of modes.)

       You can retrieve the dialog's mode with mode(). Use setFilter() to set
       the dialog's file filter, e.g.

	   fd->setFilter( "Images (*.png *.xpm *.jpg)" );

       In the above example, the filter is set to "Images (*.png *.xpm
       *.jpg)", this means that only files with the extension png, xpm or jpg
       will be shown in the QFileDialog. You can apply several filters by
       using setFilters() and add additional filters with addFilter(). Use
       setSelectedFilter() to select one of the filters you've given as the
       file dialog's default filter. Whenever the user changes the filter the
       filterSelected() signal is emitted.

       The file dialog has two view modes, QFileDialog::List which simply
       lists file and directory names and QFileDialog::Detail which displays
       additional information alongside each name, e.g. file size,
       modification date, etc. Set the mode with setViewMode().

	   fd->setViewMode( QFileDialog::Detail );

       The last important function you will need to use when creating your own
       file dialog is selectedFile().

	   QString fileName;
	   if ( fd->exec() == QDialog::Accepted )
	       fileName = fd->selectedFile();

       In the above example, a modal file dialog is created and shown. If the
       user clicked OK, then the file they selected is put in fileName.

       If you are using the ExistingFiles mode then you will need to use
       selectedFiles() which will return the selected files in a QStringList.

       The dialog's working directory can be set with setDir(). The display of
       hidden files is controlled with setShowHiddenFiles(). The dialog can be
       forced to re-read the directory with rereadDir() and re-sort the
       directory with resortDir(). All the files in the current directory can
       be selected with selectAll().

Creating and using preview widgets
       There are two kinds of preview widgets that can be used with
       QFileDialogs: content preview widgets and information preview widgets.
       They are created and used in the same way except that the function
       names differ, e.g. setContentsPreview() and setInfoPreview().

       A preview widget is a widget that is placed inside a QFileDialog so
       that the user can see either the contents of the file, or information
       about the file.

	   class Preview : public QLabel, public QFilePreview
	   {
	   public:
	       Preview( QWidget *parent=0 ) : QLabel( parent ) {}
	       void previewUrl( const QUrl &u )
	       {
		   QString path = u.path();
		   QPixmap pix( path );
		   if ( pix.isNull() )
		       setText( "This is not a pixmap" );
		   else
		       setPixmap( pix );
	       }
	   };

       In the above snippet, we create a preview widget which inherits from
       QLabel and QFilePreview. File preview widgets must inherit from
       QFilePreview.

       Inside the class we reimplement QFilePreview::previewUrl(), this is
       where we determine what happens when a file is selected. In the above
       example we only show a preview of the file if it is a valid pixmap.
       Here's how to make a file dialog use a preview widget:

	   Preview* p = new Preview;
	   QFileDialog* fd = new QFileDialog( this );
	   fd->setContentsPreviewEnabled( TRUE );
	   fd->setContentsPreview( p, p );
	   fd->setPreviewMode( QFileDialog::Contents );
	   fd->show();

       The first line creates an instance of our preview widget. We then
       create our file dialog and call setContentsPreviewEnabled( TRUE ), this
       tell the file dialog to preview the contents of the currently selected
       file. We then call setContentsPreview() -- note that we pass the same
       preview widget twice. Finally, before showing the file dialog, we call
       setPreviewMode() setting the mode to Contents which will show the
       contents preview of the file that the user has selected.

       If you create another preview widget that is used for displaying
       information about a file, create it in the same way as the contents
       preview widget and call setInfoPreviewEnabled(), and setInfoPreview().
       Then the user will be able to switch between the two preview modes.

       For more information about creating a QFilePreview widget see
       QFilePreview.

   Member Type Documentation
QFileDialog::Mode
       This enum is used to indicate what the user may select in the file
       dialog, i.e. what the dialog will return if the user clicks OK.

       QFileDialog::AnyFile - The name of a file, whether it exists or not.

       QFileDialog::ExistingFile - The name of a single existing file.

       QFileDialog::Directory - The name of a directory. Both files and
       directories are displayed.

       QFileDialog::DirectoryOnly - The name of a directory. The file dialog
       will only display directories.

       QFileDialog::ExistingFiles - The names of zero or more existing files.

       See setMode().

QFileDialog::PreviewMode
       This enum describes the preview mode of the file dialog.

       QFileDialog::NoPreview - No preview is shown at all.

       QFileDialog::Contents - Show a preview of the contents of the current
       file using the contents preview widget.

       QFileDialog::Info - Show information about the current file using the
       info preview widget.

       See setPreviewMode(), setContentsPreview() and setInfoPreview().

QFileDialog::ViewMode
       This enum describes the view mode of the file dialog, i.e. what
       information about each file will be displayed.

       QFileDialog::List - Display file and directory names with icons.

       QFileDialog::Detail - Display file and directory names with icons plus
       additional information, such as file size and modification date.

       See setViewMode().

MEMBER FUNCTION DOCUMENTATION
QFileDialog::QFileDialog ( const QString & dirName, const QString & filter =
       QString::null, QWidget * parent = 0, const char * name = 0, bool modal
       = FALSE )
       Constructs a file dialog called name with the parent, parent. If modal
       is TRUE then the file dialog is modal; otherwise it is modeless.

       If dirName is specified then it will be used as the dialog's working
       directory, i.e. it will be the directory that is shown when the dialog
       appears. If filter is specified it will be used as the dialog's file
       filter.

QFileDialog::QFileDialog ( QWidget * parent = 0, const char * name = 0, bool
       modal = FALSE )
       Constructs a file dialog called name, with the parent, parent. If modal
       is TRUE then the file dialog is modal; otherwise it is modeless.

QFileDialog::~QFileDialog ()
       Destroys the file dialog.

void QFileDialog::addFilter ( const QString & filter )
       Adds the filter filter to the list of filters and makes it the current
       filter.

	   QFileDialog* fd = new QFileDialog( this );
	   fd->addFilter( "Images (*.png *.jpg *.xpm)" );
	   fd->show();

       In the above example, a file dialog is created, and the file filter
       "Images (*.png *.jpg *.xpm)" is added and is set as the current filter.
       The original filter, "All Files (*)", is still available.

       See also setFilter() and setFilters().

void QFileDialog::addLeftWidget ( QWidget * w ) [protected]
       Adds the widget w to the left-hand side of the file dialog.

       See also addRightWidget(), addWidgets(), and addToolButton().

void QFileDialog::addRightWidget ( QWidget * w ) [protected]
       Adds the widget w to the right-hand side of the file dialog.

       See also addLeftWidget(), addWidgets(), and addToolButton().

void QFileDialog::addToolButton ( QButton * b, bool separator = FALSE )
       [protected]
       Adds the tool button b to the row of tool buttons at the top of the
       file dialog. The button is appended to the right of this row. If
       separator is TRUE, a small space is inserted between the last button of
       the row and the new button b.

       See also addWidgets(), addLeftWidget(), and addRightWidget().

void QFileDialog::addWidgets ( QLabel * l, QWidget * w, QPushButton * b )
       [protected]
       Adds the specified widgets to the bottom of the file dialog. The label
       l is placed underneath the "file name" and the "file types" labels. The
       widget w is placed underneath the file types combobox. The button b is
       placed underneath the Cancel pushbutton.

	   MyFileDialog::MyFileDialog( QWidget* parent, const char* name ) :
	       QFileDialog( parent, name )
	   {
	       QLabel* label = new QLabel( "Added widgets", this );
	       QLineEdit* lineedit = new QLineEdit( this );
	       QPushButton* pushbutton = new QPushButton( this );
	       addWidgets( label, lineedit, pushbutton );
	   }

       If you don't want to have one of the widgets added, pass 0 in that
       widget's position.

       Every time you call this function, a new row of widgets will be added
       to the bottom of the file dialog.

       See also addToolButton(), addLeftWidget(), and addRightWidget().

const QDir * QFileDialog::dir () const
       Returns the current directory shown in the file dialog.

       The ownership of the QDir pointer is transferred to the caller, so it
       must be deleted by the caller when no longer required.

       See also setDir().

void QFileDialog::dirEntered ( const QString & ) [signal]
       This signal is emitted when the user enters a directory.

       See also dir().

QString QFileDialog::dirPath () const
       Returns the file dialog's working directory. See the "dirPath" property
       for details.

void QFileDialog::fileHighlighted ( const QString & ) [signal]
       This signal is emitted when the user highlights a file, i.e. makes it
       the current file.

       See also fileSelected() and filesSelected().

void QFileDialog::fileSelected ( const QString & ) [signal]
       This signal is emitted when the user selects a file.

       See also filesSelected(), fileHighlighted(), and selectedFile.

void QFileDialog::filesSelected ( const QStringList & ) [signal]
       This signal is emitted when the user selects one or more files in
       ExistingFiles mode.

       See also fileSelected(), fileHighlighted(), and selectedFiles.

void QFileDialog::filterSelected ( const QString & ) [signal]
       This signal is emitted when the user selects a filter.

       See also selectedFilter.

QString QFileDialog::getExistingDirectory ( const QString & dir =
       QString::null, QWidget * parent = 0, const char * name = 0, const
       QString & caption = QString::null, bool dirOnly = TRUE, bool
       resolveSymlinks = TRUE ) [static]
       This is a convenience static function that will return an existing
       directory selected by the user.

	   QString s = QFileDialog::getExistingDirectory(
			   "/home",
			   this,
			   "get existing directory",
			   "Choose a directory",
			   TRUE );

       This function creates a modal file dialog called name, with parent,
       parent. If parent is not 0, the dialog will be shown centered over the
       parent.

       The dialog's working directory is set to dir, and the caption is set to
       caption. Either of these may be QString::null in which case the current
       directory and a default caption will be used respectively.

       Note on Windows that if dir is QString::null then the dialog's working
       directory will be set to the user's My Documents directory.

       If dirOnly is TRUE, then only directories will be shown in the file
       dialog; otherwise both directories and files will be shown.

       Under Unix/X11, the normal behavior of the file dialog is to resolve
       and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
       the file dialog will change to /var/tmp after entering /usr/tmp. If
       resolveSymlinks is FALSE, the file dialog will treat symlinks as
       regular directories.

       Under Windows and Mac OS X, this static function will use the native
       file dialog and not a QFileDialog, unless the style of the application
       is set to something other than the native style. (Note that on Windows
       the dialog will spin a blocking modal event loop that will not dispatch
       any QTimers and if parent is not 0 then it will position the dialog
       just under the parent's titlebar).

       See also getOpenFileName(), getOpenFileNames(), and getSaveFileName().

QString QFileDialog::getOpenFileName ( const QString & startWith =
       QString::null, const QString & filter = QString::null, QWidget * parent
       = 0, const char * name = 0, const QString & caption = QString::null,
       QString * selectedFilter = 0, bool resolveSymlinks = TRUE ) [static]
       This is a convenience static function that returns an existing file
       selected by the user. If the user pressed Cancel, it returns a null
       string.

	   QString s = QFileDialog::getOpenFileName(
			   "/home",
			   "Images (*.png *.xpm *.jpg)",
			   this,
			   "open file dialog",
			   "Choose a file to open" );

       The function creates a modal file dialog called name, with parent,
       parent. If a parent is not 0, the dialog will be shown centered over
       the parent.

       The file dialog's working directory will be set to startWith. If
       startWith includes a file name, the file will be selected. The filter
       is set to filter so that only those files which match the filter are
       shown. The filter selected is set to selectedFilter. The parameters
       startWith, selectedFilter and filter may be QString::null.

       The dialog's caption is set to caption. If caption is not specified
       then a default caption will be used.

       Under Windows and Mac OS X, this static function will use the native
       file dialog and not a QFileDialog, unless the style of the application
       is set to something other than the native style (Note that on Windows
       the dialog will spin a blocking modal event loop that will not dispatch
       any QTimers and if parent is not 0 then it will position the dialog
       just under the parent's titlebar).

       Under Unix/X11, the normal behavior of the file dialog is to resolve
       and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
       the file dialog will change to /var/tmp after entering /usr/tmp. If
       resolveSymlinks is FALSE, the file dialog will treat symlinks as
       regular directories.

       See also getOpenFileNames(), getSaveFileName(), and
       getExistingDirectory().

       Examples:

QStringList QFileDialog::getOpenFileNames ( const QString & filter =
       QString::null, const QString & dir = QString::null, QWidget * parent =
       0, const char * name = 0, const QString & caption = QString::null,
       QString * selectedFilter = 0, bool resolveSymlinks = TRUE ) [static]
       This is a convenience static function that will return one or more
       existing files selected by the user.

	   QStringList files = QFileDialog::getOpenFileNames(
				   "Images (*.png *.xpm *.jpg)",
				   "/home",
				   this,
				   "open files dialog",
				   "Select one or more files to open" );

       This function creates a modal file dialog called name, with parent
       parent. If parent is not 0, the dialog will be shown centered over the
       parent.

       The file dialog's working directory will be set to dir. If dir includes
       a file name, the file will be selected. The filter is set to filter so
       that only those files which match the filter are shown. The filter
       selected is set to selectedFilter. The parameters dir, selectedFilter
       and filter may be QString::null.

       The dialog's caption is set to caption. If caption is not specified
       then a default caption will be used.

       Under Windows and Mac OS X, this static function will use the native
       file dialog and not a QFileDialog, unless the style of the application
       is set to something other than the native style. (Note that on Windows
       the dialog will spin a blocking modal event loop that will not dispatch
       any QTimers and if parent is not 0 then it will position the dialog
       just under the parent's titlebar).

       Under Unix/X11, the normal behavior of the file dialog is to resolve
       and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
       the file dialog will change to /var/tmp after entering /usr/tmp. If
       resolveSymlinks is FALSE, the file dialog will treat symlinks as
       regular directories.

       Note that if you want to iterate over the list of files, you should
       iterate over a copy, e.g.

	   QStringList list = files;
	   QStringList::Iterator it = list.begin();
	   while( it != list.end() ) {
	       myProcessing( *it );
	       ++it;
	   }

       See also getOpenFileName(), getSaveFileName(), and
       getExistingDirectory().

QString QFileDialog::getSaveFileName ( const QString & startWith =
       QString::null, const QString & filter = QString::null, QWidget * parent
       = 0, const char * name = 0, const QString & caption = QString::null,
       QString * selectedFilter = 0, bool resolveSymlinks = TRUE ) [static]
       This is a convenience static function that will return a file name
       selected by the user. The file does not have to exist.

       It creates a modal file dialog called name, with parent, parent. If a
       parent is not 0, the dialog will be shown centered over the parent.

	   QString s = QFileDialog::getSaveFileName(
			   "/home",
			   "Images (*.png *.xpm *.jpg)",
			   this,
			   "save file dialog",
			   "Choose a filename to save under" );

       The file dialog's working directory will be set to startWith. If
       startWith includes a file name, the file will be selected. The filter
       is set to filter so that only those files which match the filter are
       shown. The filter selected is set to selectedFilter. The parameters
       startWith, selectedFilter and filter may be QString::null.

       The dialog's caption is set to caption. If caption is not specified
       then a default caption will be used.

       Under Windows and Mac OS X, this static function will use the native
       file dialog and not a QFileDialog, unless the style of the application
       is set to something other than the native style. (Note that on Windows
       the dialog will spin a blocking modal event loop that will not dispatch
       any QTimers and if parent is not 0 then it will position the dialog
       just under the parent's titlebar.

       Under Unix/X11, the normal behavior of the file dialog is to resolve
       and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
       the file dialog will change to /var/tmp after entering /usr/tmp. If
       resolveSymlinks is FALSE, the file dialog will treat symlinks as
       regular directories.

       See also getOpenFileName(), getOpenFileNames(), and
       getExistingDirectory().

       Examples:

QFileIconProvider * QFileDialog::iconProvider () [static]
       Returns a pointer to the icon provider currently set on the file
       dialog. By default there is no icon provider, and this function returns
       0.

       See also setIconProvider() and QFileIconProvider.

bool QFileDialog::isContentsPreviewEnabled () const
       Returns TRUE if the file dialog can provide a contents preview of the
       currently selected file; otherwise returns FALSE. See the
       "contentsPreview" property for details.

bool QFileDialog::isInfoPreviewEnabled () const
       Returns TRUE if the file dialog can provide preview information about
       the currently selected file; otherwise returns FALSE. See the
       "infoPreview" property for details.

Mode QFileDialog::mode () const
       Returns the file dialog's mode. See the "mode" property for details.

PreviewMode QFileDialog::previewMode () const
       Returns the preview mode for the file dialog. See the "previewMode"
       property for details.

void QFileDialog::rereadDir ()
       Rereads the current directory shown in the file dialog.

       The only time you will need to call this function is if the contents of
       the directory change and you wish to refresh the file dialog to reflect
       the change.

       See also resortDir().

void QFileDialog::resortDir ()
       Re-sorts the displayed directory.

       See also rereadDir().

void QFileDialog::selectAll ( bool b )
       If b is TRUE then all the files in the current directory are selected;
       otherwise, they are deselected.

QString QFileDialog::selectedFile () const
       Returns the name of the selected file. See the "selectedFile" property
       for details.

QStringList QFileDialog::selectedFiles () const
       Returns the list of selected files. See the "selectedFiles" property
       for details.

QString QFileDialog::selectedFilter () const
       Returns the filter which the user has selected in the file dialog. See
       the "selectedFilter" property for details.

void QFileDialog::setContentsPreview ( QWidget * w, QFilePreview * preview )
       Sets the widget to be used for displaying the contents of the file to
       the widget w and a preview of those contents to the QFilePreview
       preview.

       Normally you would create a preview widget that derives from both
       QWidget and QFilePreview, so you should pass the same widget twice. If
       you don't, you must remember to delete the preview object in order to
       avoid memory leaks.

	   class Preview : public QLabel, public QFilePreview
	   {
	   public:
	       Preview( QWidget *parent=0 ) : QLabel( parent ) {}
	       void previewUrl( const QUrl &u )
	       {
		   QString path = u.path();
		   QPixmap pix( path );
		   if ( pix.isNull() )
		       setText( "This is not a pixmap" );
		   else
		       setPixmap( pix );
	       }
	   };
	 //...
	 int main( int argc, char** argv )
	 {
	   Preview* p = new Preview;
	   QFileDialog* fd = new QFileDialog( this );
	   fd->setContentsPreviewEnabled( TRUE );
	   fd->setContentsPreview( p, p );
	   fd->setPreviewMode( QFileDialog::Contents );
	   fd->show();
	 }

       See also contentsPreview, setInfoPreview(), and previewMode.

       Example: qdir/qdir.cpp.

void QFileDialog::setContentsPreviewEnabled ( bool )
       Sets whether the file dialog can provide a contents preview of the
       currently selected file. See the "contentsPreview" property for
       details.

void QFileDialog::setDir ( const QDir & dir )
       Sets the file dialog's working directory to dir.

       See also dir().

void QFileDialog::setDir ( const QString & pathstr ) [slot]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Sets the file dialog's working directory to pathstr.

       See also dir().

void QFileDialog::setFilter ( const QString & newFilter ) [slot]
       Sets the filter used in the file dialog to newFilter.

       If newFilter contains a pair of parentheses containing one or more of
       anything*something separated by spaces or by semi-colons then only the
       text contained in the parentheses is used as the filter. This means
       that these calls are all equivalent:

	    fd->setFilter( "All C++ files (*.cpp *.cc *.C *.cxx *.c++)" );
	    fd->setFilter( "*.cpp *.cc *.C *.cxx *.c++" );
	    fd->setFilter( "All C++ files (*.cpp;*.cc;*.C;*.cxx;*.c++)" );
	    fd->setFilter( "*.cpp;*.cc;*.C;*.cxx;*.c++" );

       See also setFilters().

void QFileDialog::setFilters ( const QString & filters ) [slot]
       Sets the filters used in the file dialog to filters. Each group of
       filters must be separated by ;; (two semi-colons).

	   QString types("Image files (*.png *.xpm *.jpg);;"
			 "Text files (*.txt);;"
			 "Any files (*)");
	   QFileDialog fd = new QFileDialog( this );
	   fd->setFilters( types );
	   fd->show();

void QFileDialog::setFilters ( const char ** types ) [slot]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       types must be a null-terminated list of strings.

void QFileDialog::setFilters ( const QStringList & ) [slot]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

void QFileDialog::setIconProvider ( QFileIconProvider * provider ) [static]
       Sets the QFileIconProvider used by the file dialog to provider.

       The default is that there is no QFileIconProvider and QFileDialog just
       draws a folder icon next to each directory and nothing next to files.

       See also QFileIconProvider and iconProvider().

       Example: showimg/main.cpp.

void QFileDialog::setInfoPreview ( QWidget * w, QFilePreview * preview )
       Sets the widget to be used for displaying information about the file to
       the widget w and a preview of that information to the QFilePreview
       preview.

       Normally you would create a preview widget that derives from both
       QWidget and QFilePreview, so you should pass the same widget twice. If
       you don't, you must remember to delete the preview object in order to
       avoid memory leaks.

	   class Preview : public QLabel, public QFilePreview
	   {
	   public:
	       Preview( QWidget *parent=0 ) : QLabel( parent ) {}
	       void previewUrl( const QUrl &u )
	       {
		   QString path = u.path();
		   QPixmap pix( path );
		   if ( pix.isNull() )
		       setText( "This is not a pixmap" );
		   else
		       setText( "This is a pixmap" );
	       }
	   };
	 //...
	 int main( int argc, char** argv )
	 {
	   Preview* p = new Preview;
	   QFileDialog* fd = new QFileDialog( this );
	   fd->setInfoPreviewEnabled( TRUE );
	   fd->setInfoPreview( p, p );
	   fd->setPreviewMode( QFileDialog::Info );
	   fd->show();
	 }

       See also setContentsPreview(), infoPreview, and previewMode.

void QFileDialog::setInfoPreviewEnabled ( bool )
       Sets whether the file dialog can provide preview information about the
       currently selected file. See the "infoPreview" property for details.

void QFileDialog::setMode ( Mode )
       Sets the file dialog's mode. See the "mode" property for details.

void QFileDialog::setPreviewMode ( PreviewMode m )
       Sets the preview mode for the file dialog to m. See the "previewMode"
       property for details.

void QFileDialog::setSelectedFilter ( const QString & mask ) [virtual]
       Sets the current filter selected in the file dialog to the first one
       that contains the text mask.

void QFileDialog::setSelectedFilter ( int n ) [virtual]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Sets the current filter selected in the file dialog to the n-th filter
       in the filter list.

       See also filterSelected(), selectedFilter, selectedFiles, and
       selectedFile.

void QFileDialog::setSelection ( const QString & filename )
       Sets the default selection to filename. If filename is absolute,
       setDir() is also called to set the file dialog's working directory to
       the filename's directory.

       Example: qdir/qdir.cpp.

void QFileDialog::setShowHiddenFiles ( bool s )
       Sets whether hidden files are shown in the file dialog to s. See the
       "showHiddenFiles" property for details.

void QFileDialog::setUrl ( const QUrlOperator & url ) [slot]
       Sets the file dialog's working directory to the directory specified at
       url.

       See also url().

   Property Documentation
bool contentsPreview
       This property holds whether the file dialog can provide a contents
       preview of the currently selected file.

       The default is FALSE.

       See also setContentsPreview() and infoPreview.

       Set this property's value with setContentsPreviewEnabled() and get this
       property's value with isContentsPreviewEnabled().

QString dirPath
       This property holds the file dialog's working directory.

       Get this property's value with dirPath().

       See also dir() and setDir().

bool infoPreview
       This property holds whether the file dialog can provide preview
       information about the currently selected file.

       The default is FALSE.

       Set this property's value with setInfoPreviewEnabled() and get this
       property's value with isInfoPreviewEnabled().

Mode mode
       This property holds the file dialog's mode.

       The default mode is ExistingFile.

       Set this property's value with setMode() and get this property's value
       with mode().

PreviewMode previewMode
       This property holds the preview mode for the file dialog.

       If you set the mode to be a mode other than NoPreview, you must use
       setInfoPreview() or setContentsPreview() to set the dialog's preview
       widget to your preview widget and enable the preview widget(s) with
       setInfoPreviewEnabled() or setContentsPreviewEnabled().

       See also infoPreview, contentsPreview, and viewMode.

       Set this property's value with setPreviewMode() and get this property's
       value with previewMode().

QString selectedFile
       This property holds the name of the selected file.

       If a file was selected selectedFile contains the file's name including
       its absolute path; otherwise selectedFile is empty.

       See also QString::isEmpty(), selectedFiles, and selectedFilter.

       Get this property's value with selectedFile().

QStringList selectedFiles
       This property holds the list of selected files.

       If one or more files are selected, selectedFiles contains their names
       including their absolute paths. If no files are selected or the mode
       isn't ExistingFiles selectedFiles is an empty list.

       It is more convenient to use selectedFile() if the mode is
       ExistingFile, Directory or DirectoryOnly.

       Note that if you want to iterate over the list, you should iterate over
       a copy, e.g.

	   QStringList list = myFileDialog.selectedFiles();
	   QStringList::Iterator it = list.begin();
	   while( it != list.end() ) {
	       myProcessing( *it );
	       ++it;
	   }

       See also selectedFile, selectedFilter, and QValueList::empty().

       Get this property's value with selectedFiles().

QString selectedFilter
       This property holds the filter which the user has selected in the file
       dialog.

       Get this property's value with selectedFilter().

       See also filterSelected(), selectedFiles, and selectedFile.

bool showHiddenFiles
       This property holds whether hidden files are shown in the file dialog.

       The default is FALSE, i.e. don't show hidden files.

       Set this property's value with setShowHiddenFiles() and get this
       property's value with showHiddenFiles().

ViewMode viewMode
       This property holds the file dialog's view mode.

       If you set the view mode to be Detail (the default), then you will see
       the file's details, such as the size of the file and the date the file
       was last modified in addition to the file's name.

       If you set the view mode to be List, then you will just see a list of
       the files and folders.

       See QFileDialog::ViewMode

       Set this property's value with setViewMode() and get this property's
       value with viewMode().
